Marek Hamsik likely had other things than crime on his mind as he pulled out of the Stadio San Paolo parking lot. An hour after Napoli's 0-0 draw with Sampdoria, the midfielder might still have been reliving the chance he could not quite take, a 74th-minute daisy-cutter that Sergio Romero pushed on to the post. Perhaps, like so many of his team-mates, he was reflecting on the atrocious state of his home stadium's pitch.

But then someone stuck a pistol in his face. Hamsik had been waiting in traffic on Via Cinthia, preparing to join the Tangenziale bypass, when a scooter carrying three masked men reportedly pulled alongside his BMW. One man smashed the driver's window, before aiming a gun at Hamsik and demanding his watch – a Rolex Daytona worth upwards of €10,000 (£8,600). The player did as he was told and the scooter sped off.

For Hamsik, this was not the first time. In December 2008 he was the victim of a similar theft while Christmas shopping. Then his car was a Mini and his assailants were two instead of three but otherwise the incident was almost identical – right down to the brand of watch that was stolen.

It was widely reported in the wake of that first incident that Hamsik's watch had been returned, supposedly after the criminals realised who they had taken it from. Hamsik has denied this story. "That's what came out in the newspapers but it wasn't true," he told the Slovakian publication Pravda. "I was very sad about that watch, it was my favourite Rolex and it wasn't cheap."

Both incidents have not been the limit of Hamsik's experience with crime in Naples. In 2011 his pregnant wife, Martina, had her car stolen at gunpoint. It was later recovered thanks to a satellite tracking device.

Hamsik is yet to make any sort of public statement on Sunday's incident but his sister, Miska, made plain her feelings on Twitter. "This is the third time already," she wrote. "It's disgusting,"

We shall have to wait and see if Napoli's owner, Aurelio De Laurentiis, feels moved to respond. A little over a year ago Yanina Screpante, the girlfriend of the then Napoli forward Ezequiel Lavezzi, used the same medium to define Naples as a "shit city" after having her own watch stolen. After reading her remarks, De Laurentiis issued a few choice words of his own, saying: "In a climate of recession I think you should not go around with a Rolex on your arm." He also suggested that Screpante was "not yet Neapolitan enough".

Where the owner's relationship with Lavezzi was always tempestuous, Hamsik has been long viewed as a model player. Sixty-eight goals in five and a half seasons with the club represent a phenomenal return for a player who has shifted between roles in midfield and just behind the attack, and Hamsik's approach to his work has rarely been anything other than exemplary. He is beloved of the fans and under contract to 2016.

Those supporters will hope this latest incident has not affected his feelings about staying. Despite flirtations with Milan in the past, Hamsik has always been enthusiastic about Napoli. Yet it is hard to believe that incidents such as the one that unfolded on Sunday would not become a factor in the player's feelings about the city.

Other members of the team have also been targeted. Edinson Cavani relocated his family to a residential complex with armed security after their home was broken into. His wife had her watch stolen while out shopping, as did another Napoli player, Valon Behrami.

Crime is not a uniquely Neapolitan phenomenon. Wesley Sneijder and Samuel Eto'o had their homes burgled in Milan, while Christian Vieri and Lucio were duped into handing over their car keys to fake valets. Juan, Gabriel Heinze and Christian Panucci have been robbed at different times in Rome. Leonardo Bonucci had a gun pointed at him in Turin earlier this season, though he responded by landing a series of punches on his assailant.

But it is one thing to be aware of crime affecting others and another to be confronted with it. Hamsik may yet shrug off this latest incident but if he were to feel unsettled then few could blame him.

The player might be frustrated enough with the way things are going on the pitch after Napoli blew another chance to close the gap on Juventus at the top of Serie A. Walter Mazzarri's side had the chance to move within two points of the leaders with victory over Sampdoria but instead trail by four.

It is not the first such opportunity they have passed up. On 3 November Juventus lost 3-1 to Inter but on 4 November Napoli conceded a late equaliser at home to Torino. On 17 November Juventus were held 0-0 against Lazio in a game that kicked off at 6pm, only for the Partenopei to be held by Milan at the Stadio San Paolo later the same evening.

Napoli's players might reasonably protest that their home advantage is not as great this season as it would have been if the pitch were better maintained. In the early part of the campaign the playing surface came to resemble a poorly maintained beach, rogue tufts of grass protruding through the sand that covered most of the field after a fungus had laid waste to the rest.

On Sunday the pitch appeared passable at kick-off but very quickly began tearing apart under the feet of the players. Large clods came away with each tackle, creating a surface that was sloppy and uneven. "It's a miracle we have this many points," protested Paolo Cannavaro. "This pitch penalises the more technically gifted team."

That much may be true but Napoli still have only themselves to blame for a lethargic performance, Hamsik's strike against the woodwork represented one of few chances created. Mazzarri made eight changes to his starting XI following their Europa League humiliation by Viktoria Plzen but once again his side lacked impetus.

Cavani, largely anonymous throughout, is without a goal in four games and the team's travails in that period highlight his importance. Napoli had not failed to score at home all season prior to this week but between Plzen and Sampdoria they did so twice in four days.

Nevertheless, this was another disappointing week for Napoli. And another distressing one for Marek Hamsik.

Talking points

• Gigi Buffon twice hugged Francesco Totti before Juve's game against Roma, grabbing the forward for an embrace at the handshake and then going back in for another just before the players ran back to their teams for kick-off. In return, Totti did this. (According to reports in Sunday's papers, that ball is travelling at 71mph)

• Fiorentina's victory was every bit as emphatic as that scoreline suggests, in fact possibly even more so. They finished with 12 shots on target to Inter's one and enjoyed nearly 65% of possession. It was a triumphant return to form for a team who had previously won only once in 2013 but also a deeply troubling defeat for Inter. Andrea Stramaccioni accepted the blame, saying he had underestimated the tiredness of the players who had started the Europa League victory against Cluj three days earlier. With Inter sliding down to fifth, behind Milan, fans are beginning to ask whether he hasn't been guilty of some more significant missteps.

• Milan, by contrast, are flying as they prepare for their Champions League tie against Barcelona. The Rossoneri were nine points adrift of the top three at Christmas, but sit level on points with third-placed Lazio. The Biancocelesti have a game in hand, against Siena on Monday night, but it has nevertheless been a remarkable turnaround. And Mario Balotelli certainly continues to play his part, scoring his fourth goal in three games in the 2-1 win over Parma this weekend.

• The Cagliari owner, Massimo Cellino, remains in prison following his arrest last week as part of an investigation into the construction of the team's IS Arenas stadium. Cellino is accused of embezzlement and false representation but maintains his innocence of both charges. Both the club's players and fans appear to remain firmly in his corner. The former group dedicated their 2-0 victory over Pescara this weekend to the owner, while a group of 200 or so fans congregated outside the Buoncammino prison – where Cellino is being held – to listen to the game on radios and offer their support.
